BACKGROUND Transnasal evaporative cooling has sufficient heat transfer capacity for effective intra-arrest cooling and improves survival in swine. The aim of this study was to determine the safety, feasibility, and cooling efficacy of prehospital transnasal cooling in humans and to explore its effects on neurologically intact survival to hospital discharge.(More)
Experimental and clinical studies have provided evidence for spontaneous and therapeutically induced arteriogenesis after occlusion of major peripheral or cardiac vessels. Such evidence is lacking for the cerebrovascular system. In halothane-anesthetized rats, different degrees of brain hypoperfusion were induced by one- to four-vessel occlusion, that is,(More)
BACKGROUND Colony-stimulating factors (CSFs) have been shown to effectively induce arteriogenesis in the hindlimb. Moreover, clinical trials demonstrated positive effects of CSFs on arteriogenesis in patients with coronary artery disease. However, patients with cerebrovascular disease have not yet profited from treatments aimed at the growth of brain(More)
Stroke is the leading cause of disability and a major cause of death in Germany and the western world. Ischemic stroke involves different pathophysiologic mechanisms such as thromboembolic vascular occlusion, cerebral micro- or macroangiopathy, extracranial arterial stenosis, and cardiac embolism. Experimental and clinical studies have shown that(More)
The hospital emergency departments play a central role for the in- and outpatient care of patients with medical emergencies in Germany. In this position paper we point out some general financial and organizational problems of German emergency departments and urge for a higher significance of emergency care in the German health system as an element of public(More)
Cerebral arteriogenesis constitutes a promising therapeutic concept for cerebrovascular ischaemia; however, transcriptional profiles important for therapeutic target identification have not yet been investigated. This study aims at a comprehensive characterization of transcriptional and morphologic activation during early-phase collateral vessel growth in a(More)
INTRODUCTION Ischemia and reperfusion after cardiopulmonary resuscitation (CPR) induce endothelial activation and systemic inflammatory response, resulting in post-resuscitation disease. In this study we analyzed direct markers of endothelial injury, circulating endothelial cells (CECs) and endothelial microparticles (EMPs), and endothelial progenitor cells(More)
INTRODUCTION Microparticles are elevated in patients after successful cardiopulmonary resuscitation (CPR) and may play a role in the development of endothelial dysfunction seen in post-cardiac arrest syndrome (PCAS), a life threatening disease with high mortality. To identify mechanisms of endothelial activation and to develop novel approaches in the(More)
Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a powerful arteriogenic factor in the hypoperfused rat brain. To test the pathophysiological relevance of this response, the influence of GM-CSF on brain energy state was investigated in a model of hemodynamic stroke. Sprague-Dawley rats were submitted to three-vessel (bilateral vertebral and(More)
INTRODUCTION Ischemia/reperfusion after cardiopulmonary resuscitation (CPR) induces systemic inflammatory response and activation of endothelium and coagulation, resulting in a post-cardiac arrest syndrome. We analysed circulating (annexin V+) microparticles and their conjugates in resuscitated patients. METHODS 36 patients after successful resuscitation,(More)
